[0002] With the development of society, projection technology is more and more widely used in various fields. Projection can display images, videos and other contents in a larger size, bringing people a more shocking visual experience. Whether in business presentations, education and training or home entertainment, projection plays an important role. The emergence of micro projectors has brought great convenience to people's lives. Micro projectors are small in size and easy to carry, and can project at any time and place, meeting people's projection needs in different scenarios.
[0003] However, there are some problems in the use of existing outdoor mobile micro projectors on the market. When existing micro projectors are used outdoors, it is often difficult to adjust the height and angle. This makes it difficult for users to find a suitable projection position in different projection environments, affecting the projection effect. For example, when camping outdoors, the ground may be uneven, or the projection screen needs to be projected onto objects at different heights. If the projector cannot adjust the height and angle, it will bring great trouble to users. Summary of the Utility Model

[0013] 1. Compared with the prior art, by setting the lifting screw rod, the rotating sleeve slider, the sliding groove, the first screw hole and the projector body, when the height of the projection screen needs to be adjusted, rotate the rotating sleeve. This is because the first screw hole and the lifting screw rod are engaged with each other, and at the same time, through the cooperation of the slider and the sliding groove, the lifting screw rod can move upward, and at the same time drive the projector body to move upward together, so that the projection screen rises to a suitable position. The utility model can adjust the projector to a suitable height according to the viewing position and angle of the user to obtain a comfortable viewing angle, and avoid discomfort caused by too low or too high projection position.
[0014] 2. Compared with the prior art, by setting the ball head seat, the movable ball head, the clamping block, the bidirectional screw rod, the turning handle and the projector body, when the angle of the projection screen needs to be adjusted, the turning handle can be used to drive the bidirectional screw rod to rotate, so that the two clamping blocks move outward at the same time to loosen the movable ball head, and then adjust the angle of the projector body. After the angle is appropriate, rotate the bidirectional screw rod again to make the two clamping blocks move inward at the same time, and then the movable ball head can be clamped inside the ball head seat, so as to fix the projector body and adjust the angle of the projection screen to a suitable position. The utility model can accurately project the projection screen to a specific position, such as a wall, the side of a tent, etc., and avoid the deviation or deformation of the projection screen caused by inappropriate angle.

[0024] During use, place the bottom plate 1 at the designated position, then install the projector body 7 on the connecting rod 5, and the projection screen can be projected. When it is necessary to adjust the height of the projection screen, rotate the rotating sleeve 402. This is because the first screw hole 407 and the lifting screw rod 401 are engaged with each other. At the same time, through the cooperation of the slider 405 and the sliding groove 406, the lifting screw rod 401 can move upward, and at the same time drive the projector body 7 to move upward together, so that the projection screen rises to a suitable position. When it is necessary to adjust the angle of the projection screen, the angle can be adjusted through the adjusting component 6, and the projected screen is adjusted to a suitable position.
[0025] A movable groove 404 is formed at the top of the support rod 2, and a movable block 403 corresponding to the movable groove 404 is fixedly connected to the bottom of the rotating sleeve 402.
[0026] During use, through the cooperation of the movable block 403 and the movable groove 404, the rotating sleeve 402 can be installed on the top of the support rod 2 without affecting its free rotation.
[0027] The adjusting component 6 includes a ball head seat 601, a movable ball head 602, an installation groove 603, a clamping block 604, a connecting ear plate 605, a second fixed ear plate 606, a bidirectional screw rod 607 and a second screw hole 609. A ball head seat 601 is fixedly connected to one side of the outer wall of the installation block 3, a movable ball head 602 is fixedly connected to the outer wall of the connecting rod 5, the movable ball head 602 is movably installed inside the ball head seat 601, two symmetrically distributed installation grooves 603 are formed inside the ball head seat 601, a clamping block 604 is movably installed inside the installation groove 603, a connecting ear plate 605 is fixedly connected to the top of the clamping block 604, a second fixed ear plate 606 is fixedly connected to the top of the ball head seat 601, a bidirectional screw rod 607 is movably installed inside the second fixed ear plate 606, and second screw holes 609 corresponding to the bidirectional screw rod 607 are formed inside both connecting ear plates 605.
[0028] When it is necessary to adjust the angle of the projection screen, rotate the bidirectional screw rod 607 to make the two clamping blocks 604 move outward at the same time, loosen the movable ball head 602, then adjust the angle of the projector body 7. After the angle is appropriate, rotate the bidirectional screw rod 607 again to make the two clamping blocks 604 move inward at the same time, so that the movable ball head 602 can be clamped inside the ball head seat 601, thereby fixing the projector body 7.

[0031] One end of the connecting rod 5 far away from the movable ball head 602 is fixedly connected with a first fixed ear plate 501, and the first fixed ear plate 501 is connected to the projector body 7 through bolts.
[0032] When in use, the projector body 7 can be fixedly installed on the connecting rod 5 through bolts and the first fixed ear plate 501 for projection; when not in use, the projector body 7 can be separated from the connecting rod 5, which is convenient for users to carry the projector body 7.
[0033] Four universal wheels 8 distributed in a rectangle are fixedly installed at the bottom of the bottom plate 1.
[0034] When in use, the position of the device can be moved through the universal wheels 8, thereby moving the position of the projection screen.
[0035] Working principle: When in use, place the bottom plate 1 at the specified position, and then fixedly install the projector body 7 on the connecting rod 5 through bolts and the first fixed ear plate 501, and then the projection screen can be projected.
[0036] When it is necessary to adjust the height of the projection screen, rotate the rotating sleeve 402. This is because the first screw hole 407 and the lifting screw rod 401 are engaged with each other, and at the same time, through the cooperation of the slider 405 and the sliding groove 406, the lifting screw rod 401 can move upward, and at the same time drive the projector body 7 to move upward together, so that the projection screen rises to a suitable position.
[0037] When it is necessary to adjust the angle of the projection screen, the two clamping blocks 604 can be driven to move outward simultaneously by rotating the turning handle 608 to loosen the movable ball head 602, and then adjust the angle of the projector body 7. After the angle is appropriate, rotate the two-way screw rod 607 again to make the two clamping blocks 604 move inward simultaneously, and then the movable ball head 602 can be clamped inside the ball head seat 601, thereby fixing the projector body 7 and adjusting the angle of the projection screen to a suitable position.
